To all whom it may concern: 7 Be it known that I, WILLIAM .WINE, a citizen of the United States, resldmg at oledo, in the county of Lucas and State of bio, have invented certain new and useful Improvements in Car-Door-Locking Devices, of which the following is a specification.

My invention relates to new and useful improvements in car door locks, and has for its object to provide a lock involving a bracket or base plate designed to be secured to the side of a frei ht car and on which'is eccentrically mountegl a hook for su porting a drop bottom door both in close and in partly open position, the hook being adapted to be actuated to raise the door from its partly open ition to its sition of final closure, 1n w ich latter position it will re-' main locked until the hook is manually operated to release-the door.

As is well known to those skilled in the art, dro bottom doors are easily swung or manipu ated towards closed position until final closure is almost reached. It often happens that the doors become distorted or sition.

- Another object of the invention is to provide a hook which cooperates with a transversely mounted angle on the door to support the latter in partially closed position,v

the said hook being eccentrically mounted on the car through the intervention of a pivoted eccentric upon which said hook is rotatable, the eccentric being adapted to be rotated on its pivotal axis by means of a. wrench so as to cause the axis ofrotation of the said hook to be swung upwardly beyond the pivotal axis of the eccentric and thus raise the hook and door and lock the door in its closed position.

Anotherobje'ct of my invention is to provide an eccentricall mounted pivoted hook cooperatin with a inged door and adapted to releasab y maintain said door in either of two positions, the said hook being movable from one of said positionsto the other by a" rotation ofsaid eccentric mounting.

' A further object is to provide a hook-pivot'a'lly mounted upon an eccentrichub and adapted to releasably a door in a pluralit of positions, in combination with means or rotating said hub to move said book from either of said positions to the other. v

A still further object is to provide a locking device consisting of a bracket slilpporting an eccentric ally mounted hook an a dog for cooperating with the hook to prevent accidental release of the hook when the latter is in locked position. By reason of its 'With these and other objects in view my.

invention consists in certain novel features of construction and parts as will be hereinafter more fully described and pointed out in detail in the claims.

Referring now to the drawings showing -a preferred embodiment of the invention,-

Figure 1 is a side elevation of the locking device, and a fragmentary portion of the sideof a car, showing one edge of a drop bottom door, the door being in its closed and locked position. I

Figure 2 is a similar view, but showing the door in a temporarily supported or partly closed position, the locking dog being in its unlocked position.

Figure 3 is a detail sectional view taken taken on line .jacent its free end with a stifl'ening member 4 preferably in the form of an angle iron one end of which projects beyond the free edge of the door to afford a supporting ledge adaptedto be engaged by the coacting supporting ledge 5 o a hook 6. v

The hook 6 is ivotally mounted u n a plate or bracket which may conveniently the car side 1 1 for the be of tri ar shape and is connectedto the car side y a plurality of or rivets 8 the latter being extendedt ough and if desired through aremforcing plate. 9, as clearly shown. The bracket or plate 7 is preferably provided with a plura 11 and 12 through which the rivets 8 hereinbefore mentioned extend. The hook 6 is pivotall mounted upon the 10 in a mannerliereinafter, described, while the post 12 preferably provides a pivotal mounting locking cam or dog 13 adapted to s with the said hook for maintaining the latter in locked position. The posts 11 and 12 ma advantageously be connected b a strap or ar 14 between which and the a 'acent face of the plate 7 are positioned the ook 6 and the cam or dog 13, which pivoted parts are thereby supported againsttransverse movement. The post 11 is adapted to engage the shank of the hook 6 to limit its swing in one direction.

The hook 6 is provided at its upper end with an enlarged head 15 having a cylindrical opening 16 within which rotatably fits a circular hub 17 the latter being eccentrically and pivotally mounted upon the st 10. The ub 17 projects outwardl g om the plane of the head 15 of the hoo 6 and is cut away on opposite sides of its center so as to form a wrench receiving por- .tion.

ameter, as at 19, thus providing shoulders adapted to engage the head 15' of the hook to prevent transverse movement of the latter on the said hub.

It will be seen that when the hub 17 and hook 6 are in locked positions, as shown in Figs. 1 and 3, the hook will remain in its uppermost or locked position, as its downward pull upon the eccentric hub passes to that side of the hub pivot 10 which tends to induce a counter-clockwise or looking rotation of the hub 17. As shown in Fig. 1, the counter-clockwise rotation of the hub 17 upon the stud 10 is arrested when the hub is slightly ast dead center by the periphery of the head 15 of the hook coming into engagement with the upper end of the rib or.

stop 20 on the bracket 7. The stop 20 also acts in a similar manner, as shown in Fig. 2, to limit the clockwise or releasing rotation of the eccentric hub 17, thus controllin the extent to which the hook is lowered.

e o eration of the device is as follows ith the parts in the position shown in Fig. 2 and the door 3 open, the door can be raised by hand to the position shown .in said figure. The hook 6 being free toswing rearwardly permits the horizontal flange of the angle iron 4 to force the hook rearwardly until the flange is raised above the supporting ledge 5, whereupon the hook w1ll rop into engagement with the under face ty of hollow posts or studs 10,

The hub is slightly reduced .1n diis'psi i y 1 closed position.' To raise the door m t e position shown in Fig. .2 a wrench or other suitable toolis applied to the squared portion of the hub 17 and the latter is rotated in a counter-clockwise direction until it has assumed the position shown in Fig.

1, where, as has been already noted, the eccentric has passed slightly beyond dead center. In this position the eccentric hub forms an automatic lock for retaining the hook and door in the osition shown in Fig. 1. Thereafter the loc ing do or cam many be driven in behind the hoo%(, thus retaining the latter locked against possible disengageme'nt. To release the door it is only necessary to disengage'the cam or dog 13 and to pry or force the hook 6 rearwardly oil the edge of the angle bar 4, the hook rotatin on the c lindrical portion of the hub 1% To afl'or great strength without unduly increasing the weight 0 the parts the late or bracket 7 may be flanged on its has or inner face and the'hook 6 may also be flanged, as shown in the several figures, although, of course, this is not absolutely necessary.

From the foregoing it will be seen that I have provided a locking device which is r exceedingly simple, compact, strong and easy to operate. ue to the eccentric mounting of the hook, the door may be supported thereon in atemporary position, and while still remainingseated upon the hook may be raised toits final closed osition, suflicient force to rotate the eccentric hub 17 to thus effect an uplward movement of the hook resulting in t e closing of the (1001', being readily exerted'upon the eccentric by the application of a wrench thereto.

Many slight changes may be made without'in any way departing from the spirit and scopeof the invention.
